The FBI is searching a home in Dorchester this morning.

According to the FBI, agents are conducting “authorized activity,” but the agency won’t specify what that is or who the target might be.

WBUR’s Fred Thys is at the scene and will be providing updates. Witnesses tell Thys one arrest has been made.

The Globe reports that the Boston Police Department is working in concert with the FBI, but a spokesman for the BPD was not able to confirm that to WBUR.

UPDATE (11 a.m.): The FBI searched a house on Devon Street in Dorchester. According to area neighbors, the house belongs to a police officer, Thys said.

According to documents on the Suffolk County Registry of Deeds website, the house belonged to Vincent H. Stephens, but was foreclosed upon and now belongs to the Bank of New York. Thys is checking with BPD to see if Stephens is on the force.
